Used in biochemical and molecular biology research to detect and quantify Plant Protein Phosphatase 2C (PP2C) levels in plant tissue samples. Widely applied in studies related to plant stress responses, particularly abscisic acid (ABA) signaling pathways involved in drought tolerance and stomatal regulation. Enables researchers to monitor PP2C expression changes under environmental stresses, supporting crop improvement and plant physiology research. Suitable for high-throughput screening in agricultural biotechnology and functional genomics.
